Initiate Do Not Disturb

Someone may need to check that he is breathing okay, but other than that, this passenger has mastered the art of flying solo. He has completely cut off any form of communication with the outside world in his little self-quarantined space, and with the world in a pandemic state, he is dishing out essential pointers.

On a lighter note, some passengers just like to remain in their own world with no disturbance during their flight, and we can respect that. Shutting your eyes and plugging into music is a therapy of its own.
